Too bad I missed the BTC giveaway. Too many people are watching this thread closely now. I would have lost them on mines again probably. I have very shit luck.
If it were me, I would have wagered it on multiple games like Hi Lo or Dice since I usually like to diversify in order to try and minimize my losses.
I think the mind set behind a move like that is, "I got it for free, so it's not a big loss if I risk it all on a much bigger reward" ... I think if this was money that was funded from a monthly salary, people would not have necessarily risked it in the same way.
I have a "gambling" budget for entertainment that are funded from my wages, so I bet more carefully with that, because I want to stretch my entertainment budget to it's max for it to last longer.
I might be wrong.
